    Easy :)
    /nbt me Inventory[0].tag."Missiles 0" = 42 float

    I really need your help! The plugin works fine but:

    I have a compound with a space in it ("Inventory[0].tag.Missiles 0") and thats obviously not editable with your plugin. Do you have a clue?

    @DPOHVAR: Go

    Here is a lot more of the code via hastebin. Please tell me if you need any more information. Also, it is a bit of a mess right now, sorry.

    NPCManager http://hastebin.com/osiyefadiw.avrasm

    DataNPCSpawn http://hastebin.com/inopafofad.java

    DataNPC http://hastebin.com/ukivijoyuq.java

    All of these data fields are pulled from a SQL database.


    These lines result in the following output:

    [17:53:04 INFO]: DataLocation [id=1, x=1147.0, y=100.0, z=2256.0, world=world, pitch=0, yaw=0]
    [17:53:04 INFO]: DataNPC [id=1, custom_name=Johoon, type=ZOMBIE, is_baby=false,
    is_villager=false, gear_hands=null, gear_boots=null, gear_legs=null, gear_body=null, gear_head=null, npc_drops=null, merchant_data=null, health=200, movement_speed=0.0, follow_range=0, knockback_resistance=0, attack_damage=0, invulnerable=true, no_ai=false, can_pick_up_items=false, silent=false, can_break_doors=false]

    Hello DPOHVAR, thanks a lot for keeping this plugin working. I've been using the API and have ran into the following issue. If you have any ideas on what I'm doing wrong, please do tell. Thanks in advance.

    Hastebin link

    It'll probably be something very obvious that I'm missing. Again, thank you.

    I have artifactory repository: http://dev.bukkit.org/bukkit-plugins/powernbt/pages/repository/
    But Jenkins is really good idea!

    Hi DPOHVAR. Thanks for continuing to update this plugin. It is a thing of wonder. Perhaps do you have a Jenkins site that you use with your GitHub updates?

    Didn't expect that, the latest beta version even works with mods, that's amazing.

    Editing/saving works properly too, I'm sure there's a huge demand for this as people constantly need nbteditors for pixelmon. (Am I the only one thinking their nbt is a mess?)

    Thanks for updating this great plugin.

    @o0Julia0o: Go

    Change zombie health:
    /nbt id[Tab] HealF = 15.5
    Default zombie health is 20

    Set zombie health to maximum:
    /nbt id[Tab] HealF = this Attribues[0].base

    Change zombie maximum health:
    /nbt id[Tab] Attribues[0].base = 500

    select zombie as variable:
    /nbt %zomb select
    <then right-click on zombie>
    /nbt %zomb HealF = 1


    zombie base damage:
    /nbt %zomb Attributes[4].Base
    change base damage:
    /nbt %zomb Attributes[4].Base = 10
    zombie movement speed:
    /nbt %zomb Attributes[2].Base
